RESUMO
PURPOSE: The purpose was to compare perioperative outcomes of patients who underwent general or regional anesthesia for intramedullary (IM) nailing of tibial shaft fractures (TSFs). METHODS: Retrospective chart review was performed on a consecutive series of low-energy TSF patients who presented to a single academic medical center and a level 1 trauma center who underwent operative repair with a reamed IM nail. Collected information included demographics, injury information, anesthesia type (general or regional i.e. peripheral nerve block), intra-operative opiate consumption (converted to morphine milliequivalents [MME], and post-operative pain visual-analog scale [VAS] pain scores. Patients were divided into 3 groups based on the type of anesthesia received and univariate analysis was performed to compare the 3 groups. RESULTS: Seventy-six patients were included, with an average age of 44.47±16.0 years. There were 38 (50 %) who were administered general anesthesia and 38 (50 %) who were administered regional anesthesia in the form of a peripheral nerve block. There were no differences between the groups with respect to demographics, medical co-morbidities, rate of open fractures or AO/OTA fracture classification. Regional anesthesia patients received less intra-operative MME than general anesthesia patients (17.57±10.6, 28.96±13.8, p < 0.001). Patients who received regional anesthesia also spent less time in the operating room, received less MME on post-operative day 1, and ambulated further on post-operative day 1, however none of these differences were statistically significant. There were no cases of missed post-operative compartment syndrome or complications related to the administration of the peripheral nerve block. CONCLUSIONS: Regional anesthesia in TSF surgery received less intra-operative opioid requirements, without any untoward effects. LEVEL OF EVIDENCE: Therapeutic Level III.

PURPOSE: To investigate the qualitative and quantitative changes seen in quadriceps muscles [QM] following tibial plateau fracture and surgery. METHODS: A consecutive series of patients with an isolated tibial plateau fracture presenting to a single academic center were enrolled and prospectively followed. Bilateral knee MRIs were performed preoperatively and 3 and 12 months postoperatively to assess quantity and quality of the quadriceps muscles. All patients underwent tibial plateau operative repair and were made non-weight-bearing for 10 weeks postoperatively then advanced to weight-bearing as tolerated. Functional status assessed via the short musculoskeletal functional assessment (SMFA); knee range of motion [ROM]; vastus medialis oblique [VMO] and vastus lateralis [VL] muscle quantity (axial width, cross sectional area [CSA] and volume) on injured and contralateral limb; VMO, sartorius, semi-membranous and biceps femoris [BF] muscle quality (fat and water content, and proton density fat fraction). All muscle quantitative and qualitative measurements were compared across all time points. RESULTS: Ten patients were included in the final analysis, 6 males and 4 females, with average age of 43.62 ± 16.3 years. While the VMO and VL axial width and CSA were significantly decreased at 3 months preoperatively, this was not statistically significant. There was no significant difference between any QM quantitative measurements at any time points. There was no difference in fat content, water content or PDFF at any time point for the VMO, sartorius, semi-membranous and BF muscles. Regression analysis also showed no association between 12-month SMFA scores and knee ROM with VMO/VL CSA at 1 year. CONCLUSIONS: QM quantity and quality do not significantly change at 3 months and 1 year postoperatively following tibial plateau fracture surgery. LEVEL OF EVIDENCE: Prognostic Level II.
RESUMO
PURPOSE: To determine when patients return to work following operative repair of tibial shaft fractures (TSF) and what risk factors are associated with a delayed return to work (RTW), defined as greater than 180 days after operative repair. METHODS: Retrospective chart review was performed on a consecutive series of TSF patients who underwent operative repair. Time to RTW was based on documented work-clearance communications from the operating surgeon. Patients were divided into 3 groups based on when they returned to work: early (≤ 90 days), average (91-80 days), and late (≥ 180 days). Univariate analysis was performed, and significant variables were included in multinomial logistic regression. RESULTS: There were 168 patients identified. Eighteen were excluded (retired, unemployed, or never returned to work) leaving 150 patients. The average time to RTW for the overall study population was 4.17 ± 2.06 months. There were 39 (26.0%) patients in the early RTW group, 85 (56.7%) in the average RTW group, and 26 (17.3%) in the late RTW group. Patient with high-energy injuries (p = 0.024), open fractures (p = 0.001), initial external-fixation (p = 0.036), labor-intensive job (p = 0.018) and post-operative non-weight bearing status (p = 0.023) all had significantly longer RTW. Multinomial logistic regression including these parameters found a closed fracture was associated with a 1.9 decreased risk of delayed RTW (p = 0.004, 95% CI 0.039-0.533). CONCLUSIONS: Open fractures, initial external-fixation, restricted post-operative weight-bearing and labor-intensive jobs are associated with a delayed RTW following operative repair of TSFs. LEVEL OF EVIDENCE: Therapeutic Level III.
RESUMO
BACKGROUND: The purpose of this study was to determine if the presence of a standing Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, psychiatric diagnosis is associated with worse outcomes for patients who develop a confirmed fracture-related infection (FRI). MATERIALS AND METHODS: Included patients had open or closed fractures managed with internal fixation and had confirmed FRIs. Baseline demographics, injury information, and outcomes were collected via chart review. All patients who had a diagnosis of psychiatric illness, which included depression, bipolar disorder, anxiety disorder, and schizophrenia, were identified. Patients with and without a psychiatric diagnosis were statistically compared. RESULTS: Two hundred eleven patients were diagnosed with a confirmed FRI. Fifty-seven (27.0%) patients had a diagnosis of a psychiatric illness at the time of FRI diagnosis. Patients with a psychiatric diagnosis had a higher rate of smoking (56% vs 40%, P=.039) and drug use (39% vs 19%, P=.004) and a higher American Society of Anesthesiologists (ASA) classification (2.35±1.33 vs 1.96±1.22, P=.038); however, there were no other demographic differences. Clinical outcomes also did not differ between the groups, as patients with an FRI and a psychiatric diagnosis had a similar time to FRI diagnosis, similar confirmatory FRI characteristics, and a similar rate of reoperation. Furthermore, there was no difference between patients with FRI with and without a psychiatric diagnosis regarding rate of infection resolution (89% vs 88%, P=.718) or time to final follow-up (20.13±24.93 vs 18.11±21.81 months, P=.270). CONCLUSION: The presence of a psychiatric diagnosis does not affect clinical outcomes in the patient population with FRI. This is the first study exploring the impact of psychiatric illness on patient outcomes after a confirmed FRI diagnosis. [Orthopedics. 2024;47(4):198-204.].

PURPOSE: Determine if any fracture characteristics or radiographic parameters were predictive of fixation failure [FF] within 1 year following cephalomedullary nailing for intertrochanteric fractures. METHODS: A consecutive series of intertrochanteric hip fracture patients (AO/OTA 31A) treated with a cephalomedullary nail were reviewed. Pre-fixation (neck-shaft angle [NSA], distance from ischial tuberosities to greater and lesser trochanters, integrity of lesser trochanter, and fracture angulation) and post-fixation (post-fixation NSA, posteromedial cortex continuity, lag screw position, tip to apex distance [TAD], and post-fixation angulation and translation) radiographic parameters were measured by blinded independent reviewers. The FF and non-FF groups were statistically compared. Logistic regression was performed to determine radiographic parameter correlates of FF. RESULTS: Of 1249 patients, 23 (1.8%) developed FF within 1 year. The FF patients were younger than their non-FF counterparts (77.2 years vs 81.0 years, p=0.048), however there were no other demographic differences. The FF cohort did not differ in frequency of TAD over 25 mm (4.3% vs 9.6%, p=0.624) and had decreased mean TAD (13.6mm vs 16.3mm, p=0.021) relative to the non-FF cohort. The FF cohort had a higher rate of a post-fixation coronal plane NSA more than 10° different from the contralateral side (delta NSA>10°, 34.8% vs 13.7%, p=0.011) with the majority fixed in relative varus. For every 1° increase in varus compared to the contralateral side the odds of FF increased 7% (OR=1.065, 95%CI[1.005-1.130], p=0.034) on univariate analysis. On univariate logistic regression, patients with an absolute post-fixation NSA of 10° or more of varus compared to contralateral were significantly more likely to have a FF (OR=3.139, 95%CI[1.067-8.332], p=0.026). CONCLUSION: Despite an acceptable TAD, post-fixation NSA in relative varus as compared to the contralateral side was significantly associated with failure in intertrochanteric hip fractures fixed with a cephalomedullary nail. LEVEL OF EVIDENCE: Prognostic Level III.

Case: A 51-year-old woman with an infected left humeral shaft recalcitrant nonunion presented 3 years after initial injury. This case report focuses on the staged treatment of a 17-centimeter (cm) humeral shaft nonunion with the induced membrane technique (IMT) using a unique fixation construct of dual locked plating around a humeral nail to provide long-lasting fixation and allow for bone graft consolidation. Conclusion: Large segmental bone loss of the humerus can be treated with the IMT using nail-plate fixation constructs that allow for early mobilization, increased time for bone graft consolidation before hardware failure, and less frequent follow-up.
RESUMO
There are several eponyms used in the assessment and management of calcaneus fractures. However, the origin of these eponyms is no longer widely known. Named for orthopaedic surgeons who made substantial contributions to the management of calcaneus fractures as well as the field of orthopaedic surgery, understanding the context of how these descriptors were derived helps give context to their use in the present day. The purpose of this review is to provide a historical perspective and comprehensive collection of the most common eponyms related to calcaneus fractures.

Purpose: This study aims to compare patients in whom fixation failure occurred via cut-out (CO) or cut-through (CT) in order to determine patient factors and radiographic parameters that may be predictive of each mechanism. Materials and Methods: This retrospective cohort study includes 18 patients with intertrochanteric (IT) hip fractures (AO/OTA classification 31A1.3) who underwent treatment using a single lag screw design intramedullary nail in whom fixation failure occurred within one year. All patients were reviewed for demographics and radiographic parameters including tip-to-apex distance (TAD), posteromedial calcar continuity, neck-shaft angle, lateral wall thickness, and others. Patients were grouped into cohorts based on the mechanism of failure, either lag screw CO or CT, and a comparison was performed. Results: No differences in demographics, injury details, fracture classifications, or radiographic parameters were observed between CO/CT cohorts. Of note, a similar rate of post-reduction TAD>25 mm (P=0.936) was observed between groups. A higher rate of DEXA (dual energy X-ray absorptiometry) confirmed osteoporosis (25.0% vs. 60.0%) was observed in the CT group, but without significance. Conclusion: The mechanism of CT failure during intramedullary nail fixation of an IT fracture did not show an association with clinical data including patient demographics, reduction accuracy, or radiographic parameters. As reported in previous biomechanical studies, the main predictive factor for patients in whom early failure might occur via the CT effect mechanism may be related to bone quality; however, conduct of larger studies will be required in order to determine whether there is a difference in bone quality.
RESUMO
Purpose: To determine the effect of perioperative angiotensin II receptor blocker (ARB) or angiotensin-converting enzyme inhibitors (ACEi) on postoperative arthrofibrosis, as defined by requiring manipulation under anesthesia (MUA) or new diagnosis of adhesive capsulitis (AC) following arthroscopic shoulder procedures. Methods: Patients were retrospectively identified using Current Procedural Terminology surgical billing codes to identify patients who underwent any shoulder arthroscopic procedure at a single urban academic institution from 2012 to 2020 with a minimum 2-year follow-up. Patients were excluded if <30 years old at time of surgery, as these patients rarely use ARB and ACEi medications, or if they had pre-existing AC. Demographics, active medication prescriptions at the time of surgery, and medical comorbidities were recorded. Multivariable logistic regression was performed to determine the effect of ARB/ACEi on subsequent MUA or AC by 90 days, 1 year, and 2 years. Results: In total, 5,559 patients were included in the final analysis. A majority of the cohort (53.4%) underwent arthroscopic surgery between the ages of 50 to 69 years. Most patients were male (61.8%) and without obesity (67.3%). In total, 18.9% and 15.0% were taking an ARB or ACEi medication perioperatively, respectively. Within 2 years' postoperatively, 51 patients (0.9%) underwent subsequent ipsilateral MUA, and 174 patients (3.1%) developed AC. Patients taking ARBs had a 17.5% rate of postoperative arthrofibrosis within 2-years compared with 19.1% in those not on ARBs, although this difference was not significant (P = .58). Likewise, no significant difference was found between those taking ACEi versus not (15.0% vs 15.0%, P = .99). Individual generic ARB/ACEi subgroup analysis did not demonstrate any significant associations with rate of postoperative arthrofibrosis (P > .05). Conclusions: ARBs or ACEi did not significantly affect the rate of postoperative arthrofibrosis following shoulder arthroscopy, however female sex, diabetes mellitus, and Black/African American race were associated with an increased rate of necessitating MUA or developing AC within 2 years postoperatively. Level of Evidence: Level III, retrospective cohort study.
RESUMO
OBJECTIVE: To assess the ability of a modified frailty index (mFI-5) score, which includes the presence of congestive heart failure, hypertension, chronic obstructive pulmonary disease, diabetes, and nonindependent functional status, and to identify patients at increased risk of complications after surgical treatment of long-bone nonunions/malunions. DESIGN: Retrospective. SETTING: Hospitals participating in the 2005-2018 American College of Surgeons National Surgical Quality Improvement Program. PATIENTS/PARTICIPANTS: Patients in the American College of Surgeons National Surgical Quality Improvement Program database with upper extremity and lower extremity fractures were enrolled. INTERVENTION: Surgical repair of nonunions/malunions of upper and lower extremity long bones. MAIN OUTCOME MEASURE: Postoperative complications after long-bone nonunion/malunion surgery. RESULTS: Respective univariate analysis of the 2964 UE [1786 (60.3%) with mFI-5 of 0 and 386 (13.0%) with mFI-5 ≥2] and 3305 LE [1837 (55.6%) with mFI-5 of 0 and 498 (15.1%) with mFI-5 ≥2] showed that increasing mFI-5 score was associated with medical complications, extended longer length of stay, adverse discharge, and readmission. Binomial logistic regression showed that UE patients with mFI-5 ≥2 had increased risk of wound complications [odds ratio (OR) 2.512, 95% (confidence interval) CI: 1.037-6.086, P = 0.041), adverse discharge (OR 1.735, 95% CI: 1.204-2.499, P = 0.003), and unplanned readmission (OR 2.102, 95% CI: 1.038-4.255, P = 0.039), while LE patients with mFI-5 ≥2 had an increased risk of medical complications (OR 1.847, 95% CI: 1.307-2.610, P = 0.001), cumulative morbidity (OR 1.835, 95% CI: 1.342-2.510, P < 0.001), extended longer length of stay (OR 1.809, 95% CI: 1.233-2.654, P = 0.002), and adverse discharge (OR 1.841, 95% CI: 1.394-2.432, P < 0.001). CONCLUSIONS: mFI-5 score ≥2 is associated with significant increase in postoperative complications after surgical repair of long-bone nonunions/malunions. LEVEL OF EVIDENCE: Prognostic Level III.

PURPOSE: Electric scooters (e-scooters) have become an increasingly popular mode of public transportation in recent years. As the incidence of related injuries rises, it is important to understand specific fracture patterns unique to e-scooters and electric bikes (e-bikes) to help guide management. The purpose of this study was to review the prevalence and describe specific fracture patterns of e-scooter and e-bike related injuries at the busiest level 1 trauma center in the borough of Manhattan. METHODS: Chart review to determine mechanism of injury was performed on all patients for whom an orthopedic consult was requested from 1/1/2021 to 12/31/2021. All patients whose injuries were sustained due to an e-scooter or e-bike were further reviewed for demographics, injury characteristics including fracture pattern, and definitive injury management. Any patients who had an orthopedic consult placed for a reason other than an acute injury were excluded. Descriptive statistics are reported as frequency (percentage) for categorical variables and means for continuous variables. RESULTS: Of the 1815 orthopedic consults requested, 1357 (74.8%) were for acute injury management. Of those with acute injuries, 119 (8.8%) sustained 136 e-scooter or e-bike related injuries. There were 92 (77.3%) males at an average age of (33.8 ± 15.7) years. Approximately one-fifth of all patients presented in June 2021 (26, 21.8%). There was a 9.2% rate of open fractures. The 136 injuries were evenly split between the upper and lower extremities, with 57 (47.9%) upper extremity, 57 (47.9%) lower extremity injuries, and 5 (4.2%) concomitant upper and lower extremity injuries. The most common fracture patterns were ankle fractures (16, 11.7%), followed by tibial shaft (14, 10.2%), tibial plateau (13, 9.5%), and radial head fractures (11, 8.0%). There was a 33.3% incidence of associated posterior malleolar fractures in the spiral tibial shaft fractures, 31.0% of posterior malleolar involvement and 18.8% of isolated vertical medial malleolar fractures in the ankle fractures, and 61.5% of posterior comminution in the tibial plateau fractures. CONCLUSION: E-scooter and e-bike related injuries have a high incidence of tibial shaft fractures, ankle fractures, tibial plateau fractures, and radial head fractures. There should be a high index of suspicion for posterior and medial involvement in lower extremity fractures sustained due to e-scooter or e-bikes. Identifying specific fracture patterns seen in e-scooter and e-bike related mechanisms will help guide management of these injuries.

INTRODUCTION: The purpose of this study is to identify optimal threshold hemoglobin (Hgb) and hematocrit (Hct) laboratory values to transfuse hip fracture patients. METHODS: A consecutive series of hip fracture patients were reviewed for demographic, clinical, and cost data. Patients receiving an allogeneic transfusion of packed red blood cells (pRBCs) were grouped based on last Hct or Hgb (H&H) value before first transfusion. Multivariate logistic regressions of H&H quantile were performed to predict "good outcomes," a composite binary variable defined as admissions satisfying (1) no major complications, (2) length of stay below top tertile, (3) cost below median, (4) no mortality within 30 days, and (5) no readmission within 30 days. Odds ratios (OR) for "good outcomes" were calculated for each H&H quantile. RESULTS: One thousand four hundred ninety-six hip fracture patients were identified, of which 598 (40.0%) were transfused with pRBCs. Patients first transfused at Hgb values from 7.55 to 7.85 g/dL ( P = 0.043, OR = 2.70) or Hct values from 22.7 to 23.8% ( P = 0.048, OR = 2.63) were most likely to achieve "good outcomes." DISCUSSION: The decision to transfuse patients should be motivated by Hgb and Hct laboratory test results, given that transfusion timing relative to surgery has been shown to not affect outcomes among patients matched by trauma risk score. Surgeons should aim to transfuse hip fracture patients at Hgb levels between 7.55 g/dL and 7.85 g/dL or Hct levels between 22.7% and 23.8%. These transfusion thresholds have the potential to lower healthcare costs without compromising quality, ultimately resulting in less costly, efficacious care for the patient. LEVEL OF EVIDENCE: Level III.

PURPOSE: To (1) determine if any injury characteristics or radiographic parameters of tibial shaft fractures (TSFs) could predict posterior malleolar fracture (PMF) size, and (2) identify characteristics of PMFs that were fixed versus those that were not in a cohort of ipsilateral TSFs that underwent intramedullary nailing. METHODS: A cross-sectional radiographic study was performed at a single academic institution. Demographic and radiographic parameters of TSFs were recorded, including fracture obliquity angle (FOA) and distance from distal extent of fracture to plafond (DFP). Using CT, the PMFs were evaluated for Haraguchi classification, size measurements, and preoperative displacement. Multivariate regression analysis was used to identify independent predictors of PMF Harachuchi classification, size parameters, and preoperative displacement. Univariate differences between PMF that were fixed and not fixed were identified. RESULTS: 47 (50%) PMF underwent surgical fixation with 47 treated conservatively. There were no demographic differences between groups. Multivariate linear regression demonstrated increasing DFP and high energy injury mechanism as independent variables correlated with plafond surface area involvement, PMF height and width on sagittal CT cuts. Increasing DFP alone was correlated with PMF width on axial CT cuts and extent > 50% into incisura. Haraguchi type II fractures were associated with high energy injury mechanism (OR = 4.2 [95% CI = 1.3-14.5]; p = 0.02). Odds of Haraguchi type 3 fractures increased 9% per increased year of age (OR = 1.09 [95% CI = 1.04-1.16]; p = 0.006) and decreased 13% per 1% increase in relative DFP (OR = 0.87 [95% CI = 0.75-0.98]; p = 0.04). CONCLUSIONS: An increasing DFP of TSFs and high energy injury mechanism were independent predictors of PMF size, and high energy injury mechanism was also correlated with Haraguchi type II fracture patterns. Increasing age and decreasing DFP of TSFs predict Haraguchi type III PMF patterns. These radiographic parameters should prompt surgeons to plan for fixation in scenarios in which CT scan is not available. LEVEL OF EVIDENCE: Diagnostic Level III.

BACKGROUND: The purpose of this study was to identify specific radiographic parameters that are predictive of associated PM fractures in TSFs. METHODS: All TSFs presenting over a 6-year period were identified. A review of plain radiographs and CT scans included: identification of an isolated PM fracture, AO/OTA classification, measurements of the fracture obliquity angle (FOA), absolute and relative distance from distal extent of fracture to plafond (DFP and DFP%), and presence and level of associated fibular fractures. Patients with and without PM fractures were compared. Multivariate logistic regression determined independent correlates of PM fractures and cutoff values for FOA and DFP%. RESULTS: A total of 405 TSFs in 397 patients were identified, and 94 TSFs (23.2%) had an associated PM fracture. The majority (85.1%) of TSFs with PM fractures were AO/OTA type 42-A1, 42-B1 or 42-C1 (p < 0.001). The mean FOA was 60.9 ± 12.1° in the PM group versus 40.8 ± 18.9° in the non-PM group (p < 0.001). The mean DFP was 5.9 ± 2.7 cm in the PM group versus 11.9 ± 7.9 cm in the non-PM group (p < 0.001). Multivariate regression demonstrated that AO/OTA classification type 42-A1, 42-B1 or 42-C1 (OR 4.7 [95% CI 2.4-9.8]; p < 0.001), FOA greater than 45° (OR 4.4 [95% CI 1.9-10.9]; p = 0.001) and fracture extension to the distal third of the tibia (DFP% < 33%; OR 18.3 [95% CI 3.8-330.4]; p = 0.005) were independent correlates of PMs fractures regardless of mechanism of injury or fibula fracture presence or location (AUROC 0.83 [95% CI 0.80-0.87]). Separate multivariate regression showed for every 1° increase in FOA, PM fracture odds increase 6% per degree and for every 1 cm increase in DFP odds of PM fracture decreased by 15%. CONCLUSIONS: Spiral fractures (simple, wedge or complex), fracture angles greater than 45° and extension into the distal 1/3 of the tibial shaft are independent predictors of PM fractures in TSFs regardless of mechanism of injury.

BACKGROUND: The association of tibial shaft fractures (TSFs) with posterior malleolar fractures is well described. The purpose of this study was to identify specific radiographic parameters that are predictive of any pattern of associated distal intra-articular fractures in TSFs. METHODS: All TSFs presenting over a 6-year period were identified. A radiographic review of plain radiographs and CT scans included: identification of any associated ankle fracture, classification using the OTA System, measurements of the TSF obliquity angle (FOA), relative distance from distal extent of the TSF to plafond (DFP%), and presence and level of any associated fibular fractures. Patients with and without associated ankle fractures were statistically compared. Multivariate logistic regression determined independent predictors of associated ankle fractures. RESULTS: 405 TSFs in 397 patients were identified, with 145 TSFs with associated distal intra-articular fractures. There were 94 (23.2%) posterior malleolar fractures, 19 (13.1%) medial malleolar fractures, 42 (29.0%) lateral malleolar fractures involving the syndesmosis and 14 (9.7%) Chaput fragments. Multivariate regression demonstrated AO/OTA classification type 42-A1, 42-B1 or 42-C1 (OR 2.3 [95% CI 1.3-4.0]; p = 0.003), FOA greater than 45° (OR 2.7 [95% CI 1.5-4.8]; p = 0.001) and DFP% less than 33% (OR 4.1 [95% CI 2.0-9.0]; p = 0.005) were independent correlates of associated ankle fractures regardless of mechanism of injury. CONCLUSIONS: Different patterns of intra-articular fractures beyond posterior malleolar fractures can occur in TSFs. Fracture angles greater than 45° and extent into the distal 33% of the tibial shaft are independent predictors of distal intra-articular fractures in TSFs regardless of mechanism of injury. LEVEL OF EVIDENCE: Diagnostic Level III.

PURPOSE: The purpose of this study was to investigate if early postoperative ambulation metrics affect hospital quality measures and 1-year outcomes in operative hip fracture patients. METHODS: A consecutive series of hip fracture patients [OTA/AO 31A, 31B, 32A-C] who underwent operative treatment were reviewed for demographic and clinical data. Chart review was performed to determine participation with physical therapy [PT] and ambulation distance on postoperative day (POD) 1, 3, and 5. POD1 ambulators and non-ambulators were statistically compared. Outcome correlates of postoperative ambulation distance were investigated by univariate and multivariate linear and logistic regression. RESULTS: 1044 patients were identified with 546 (52.3%) able to ambulate on POD1. Those able to ambulate on POD1 were significantly younger (78.4 ± 10.9 vs. 82.1 ± 10.4, p < 0.001), had fewer co-morbidities (CCI 1.22 ± 1.60 vs. 1.73 ± 1.82, p < 0.001), and were more likely to be preoperative community ambulators (82.2% vs. 68.3%, p < 0.001). Patients unable to ambulate on POD1 had significantly higher rate of inpatient mortality (2.8% vs. 0.5%, p = 0.004), 1-year mortality (14.6% vs. 6.9%, p < 0.001), and a longer length of stay (7.94 ± 4.73 vs. 6.43 ± 4.02 days, p < 0.001). Non-ambulators more often required the intensive care unit postoperatively (18.7% vs. 7.1%, p < 0.001), and had increased rates of major complications (15.5% vs. 5.7%, p < 0.001). Patients with OTA 31B or 32A fractures were 1.63 times more likely to ambulate on POD1 while patients with an assistive device at baseline were 0.51 times less likely to ambulate on POD1. Increasing postoperative ambulation distance correlated with shorter length of stay (p < 0.001 for POD1, 3, and 5) and every foot walked was associated with 0.57% decreased odds of a hospital complication (p = 0.0353). CONCLUSIONS: Failure to ambulate on POD1 following hip fracture surgery in >55 years is associated with an increased risk of in-hospital complications and mortality. Every effort should be made address this modifiable risk factor and mobilise patients on POD1 to improve patient outcomes.

â¢: Approximately 25% of all patients who sustain perilunate dislocations present in a delayed fashion. â¢: While management of acute injuries is relatively well-described, treatment of chronic injuries can be complex and there is a paucity of scientific evidence to guide management. â¢: Treatment options include open reduction internal fixation, proximal row carpectomy, scaphoid or lunate excision with or without arthrodesis, and total wrist arthrodesis, although indications vary based on chronicity of injury and patient factors. â¢: The purpose of this article was to determine the quality of evidence supporting surgical options for the treatment of these injuries.

Introduction: The purpose is to investigate the incidence of wound complications for total knee arthroplasty (TKA) following tibial plateau open reduction and internal fixation (ORIF). Materials and Methods: A prospective arthroplasty registry was queried for patients with CPT codes for primary TKA, tibial plateau ORIF, removal of hardware (ROH), and diagnosis of post-traumatic arthritis. Patients were included if they had undergone tibial plateau ORIF and subsequent TKA. Chart review was performed to obtain demographic, clinical and post-operative information. Results: Twenty-one patients were identified, with average age of 56.23 ± 13.2 years at time of tibial plateau ORIF and 62.91 ± 10.8 years at time of TKA. Seven (33.3%) patients had a tibial plateau fracture-related infection (FRI). Eight (38.1%) patients underwent ROH prior to TKA. Seven (33.3%) patients' TKA incision incorporated the prior plateau incisions. Eight (36.4%) patients developed wound complications following TKA and 5 (23.8%) developed an acute periprosthetic joint infection (PJI) following TKA and had the plateau incision incorporated into the TKA incision. FRI history did not increase the rate of wound complications but did increase the rate of ROH prior to TKA. Conclusions: Previous FRI involving tibial plateau repair surgery doesn't correlate with PJI after conversion TKA for post traumatic OA. Surgeon-controlled factors such as staged ROH and incision placement can help reduce the rate of wound complications following TKA performed after tibial plateau ORIF. Level of Evidence: Prognostic Level IV. Supplementary Information: The online version contains supplementary material available at 10.1007/s43465-022-00709-1.
